L3 CHANNEL structure for timing budget, insertion loss, return loss, crosstalk, and complete channel. Numeric PASS/FAIL only from existing channel FACT; otherwise a visible skip. No OpenEMS, no invented S-parameters, no M6 packs.
Controller-aware per-memory instances, DQ/DQS vs addr/cmd/ctrl/ck, HBM not classic DDR PCB DQ. No universal mm/ps. No M6 packs, no L3 solver.
